I'm a first-year university student. Right now, we're going over completely uninteresting topics that I’ve either already covered (or skipped) back in school. I have no motivation to complete the assignments because these subjects don’t interest me at all. I know that in the future there will be subjects I’ll enjoy, but for now, I’m stuck with all of this – and without any motivation.
As a result, I end up doing nothing all day, finding ways to distract myself just to avoid working on my university assignments. I don't like this at all because I’m not doing what I actually want to do. I "wait" until late at night, realizing I can’t procrastinate any longer, or I end up sacrificing sleep. It feels like a waste of time because I’m neither doing what I have to do nor what I want to do.
This is not great advice, but I just go the Shia Lebouf method. I just tell myself to "Just do it!". If I need to do something and there's no way around not doing it, then it's just a matter of time when that deadline happens and I'll be more stressed with cramming. So I might as well do it and get it over with.
